毫米波雷达信号功率电平测量

Measurement of Power Level of Millimeter-Wave Radar Signal

FMCW Chirp是毫米波雷达主要应用的调频技术。各个国家和地区的法规和标准均规定了FMCW Chirp信号的峰值和平均值功率电平限值。为了准确测量FMCW Chirp信号的功率电平,需要确定FMCW Chirp信号的时域特性,采用合适的测量仪器,并考虑测量仪器对FMCW Chirp信号的响应特性,同时进行合适的扫描参数设置,才能获得具有较小误差的测量结果。本文还给出了测量仪器设置的一般性指引。

FMCw Chirp is the man modulation technology used in millimeter wave radar.The regulations and standards of various countries and regions specify the peak and average power level limits for the FMCW Chirp signals.In order to accurately measure the power level of the FMCW Chirp signals,it is necessary to determine the time-domain characteristics of the FMCw Chirp signals,use the suitable measuring instruments,and consider the response characteristics of the measuring instrument to the FMCw Chirp signal,and at the same time configure the appropriate sweeping parameters,in order to obtain a measurement results with small errors.This article also gives general guidelines for measuring instrument setup.
